CONTAINER CLOSURE Filed Dec. 12. 1947 E J 58 lllli Q INVENTOR. A271/025. SMITH v v ATTORNEY Patented Oct. 3, 1950 UNITED STATES PATENTOFFICE CONTAINER CLOSURE Arthur E. SmithQLos Angeles, Calif. ApplicationDecember 12, 1947, Serial no; 791,428

This invention relates to a container closure.

The general object of the invention is to provide a closure for use onbottles and other containers and wherein the closure is of an improvedtype providing for the ready preparation of a fresh solution.

Another object of the invention is to provide a novel container closurewhich includes a stop per portion and a resilient and/or flexibleportion, the movement of which causes a tablet to be released into avehicle in the container to thus prepare a fresh solution.

A further object of the invention is to provide a container closureincluding a displaceable or rupturable portion and whereinrnovement of atubular member carried by a, portion of the closure serves to ,displaceor break the rupturable portion after which a hypodermic needle may beinserted through the tubular member to extract the preparation.

A further object of the invention is to provide a closure having atubular member therein and wherein the closure may be pierced by ahypodermic needle which may then pass through the tubular portion intothe container to extract the contents of the container.

Other objects and advantages of my invention will be apparent from thefollowing description taken in connection with the accompanyingdrawings, wherein:

The figure is a central, sectional view, showing a portion of acontainer with my improved closure thereon.

In the figure I show my invention wherein a bottle 4!), having a neck 4|and a collar 42, is provided with a closure 43 which has an internallyflanged skirt 44 engaging the collar 42. The closure 43 includes aninwardly directed sleeve portion 45 which has an axial recess 46 and areduced recess 41 in which a tablet 48 is arranged. A sealing disc 49 inthe recess 46 serves to hold the tablet in place and normally preventits contact with the vehicle 50 in the bottle. The stopper includes anoutwardly opening axial recess closed at the inner end by a diaphragm52. A flexible cap 53, having a skirt 54 and a bead 55, engages theclosure 43. The upper end of the cap 53 has a collar 56 which may bemolded therein. The collar 56 includes a hole 51 which communicates witha piercing member or tube 58, the lower end of which is sharpened as at59.

In using the closure, the cap 53 is depressed,

. 4C1aims. (Cl.l28---272) thus pushing inwardlly the tube 58, the sharp-55 ened end 59 of which piercesthe diaphragm 52 and thus engages thetablet and thereafter causes removal of the disc 49 so that a freshsolution is prepared.

The disc 49 is inert in the solution made from the preparation 48 anddoes not contaminate the solution.

In the present Within the auxiliary In applicants copending applicationSer. No.

4,089, filed January 24, 1948, the claim is directed to the main andouter closure, wherein the main closure includes a cupped diaphragmportion and the outer closure includes a stem which engages 31:16 cuppedportion to cause release of a sealing isc.

In copending application Ser. No. 4,193, filed January 24, 1948, theclaim is directed to the closure which includes a corrugated diaphragmengageable by a releasing stem carried by an auxiliary closure.

In copendin-g application Ser. No. 791,429, filed December 12, 1947, theclaims are directed to a main and an auxiliary closure, with a flangedpiercing member extending through a hole in the auxiliary closure andmovable with the auxiliary closure to displace a sealing disc carried bythe main closure.

From the foregoing description it will be apparent that I have inventeda novel container closure which can be economically manufactured andwhich is highly efficient for its intended purpose.

Having thus described my invention, I claim:

1. A closure comprising a main body portion and a flexible integral endclosure portion, said main body portion having an axial recess therein,sealing means closing said recess, a medicinal tablet in said recess,sealing means closing the inner end of said recess, said body portionhaving an axial hole therein extending outwardly from said sealingmeans, and a tubular piercing member having a lower end disposed in saidhole, said tubular piercing member having a flange thereon, said endclosure member having a recess receiving said flange, said tubularmember being movable with said end closure portion to release saiddiscs.

2. A closure comprising a main body portion and a flexible auxiliaryclosure portion, said main body portion having a skirt adapted to engagethe outer surface of the neck of a bottle, said body portion having asleeve portion adapted to fit within a bottle neck, said sleeve portionhaving an axial recess, a sealing disc closing said recess, a medicinaltablet in said recess, a diaphragm closing the inner end of the recess,said body portion having an axial hole therein extending outwardly fromsaid diaphragm, said auxiliary closure including a body having a skirtthereon, said last mentioned skirt engaging the periphery of said bodyportion, and a tubular piercing member having a sharpened lower enddisposed in said hole, said tubular piercing member having a flangethereon, said flange being embedded in said auxiliary closure member.

3. A closure comprising a main body portion and an auxiliary closureportion, said main body portion having a skirt adapted to engage theouter surface of the neck of a bottle, said body portion having a sleeveportion adapted to fit within a bottle neck, said sleeve portion havingan axial recess therein and having a second axial recess smaller thanthe first recess, a sealing disc in said first recess, a medicinaltablet in said second recess, a diaphragm closing the inner end of theinner recess, said body portion having an axial hole therein extendingoutwardly from said diaphragm, said auxiliary closure including aflexible body having a skirt thereon, said skirt engaging the peripheryof said body portion, a tubular piercing member having a sharpened lowerend disposed in said hole, said tubular piercing member having a flangethereon, said flange being embedded in said auxiliary closure member,said outer periphery of said outer auxillary closure member having anindentation aligned with said tubular member, said tubular piercingmember being movable with said auxiliary closure member when the latteris flexed to puncture said diaphragm and enter the recess 4 and releasethe sealing disc.

4. A closure comprising a main body portion and an auxiliary closureportion, said main body portion having a skirt adapted to engage theouter surface of the neck of a bottle, said skirt having an internalflange adapted to engage beneath a bottle neck flange, said skirt alsohaving an external flange, said body portion having a sleeve portionadapted to fit within a bottle neck, said sleeve portion having an axialrecess therein and having a second axial recess smaller than the firstrecess, a sealing disc in said first recess, a medicinal tablet in saidsecond recess, a diaphragm closing the inner end of the inner recess,said body portion having an axial hole therein extending outwardly fromsaid diaphragm, said auxiliary closure including a flexible body havinga skirt thereon, said skirt engaging the periphery of said body portionand engaging the flange on said body portion, said auxiliary closureskirt having an external flange thereon, and a tubular piercing memberhaving a sharpened lower end disposed in said hole, said tubularpiercing member having a flange thereon, said flange being embedded insaid auxiliary closure member, said outer periphery of said outerauxiliary closure member having an indentation aligned with said tubularmember, said tubular piercing member being movable with said auxiliaryclosure member when the latter is flexed to puncture said diaphragm andenter the recess and release the sealing disc.
